GREASE-CUP.

Application filed May 23, 1916. Serial No. 99,402.

To all whom it may concern Be it known that I, Isaac H. ROHRER,

a citizen of the United States, residing at Los 'Angeles, in the countyof Los Angeles and State of California, have invented new and usefulImprovements in Grease-Cups, of which the followingis a specification.

My invention relatesto improvements in grease-cups in which a cap isscrewed over a body-member for the reception of lubri cant, which may besqueezed or injected into a bearing by the movable interengaging of thecap andthe body; and the objects of my improvements are, to simplify thefilling of grease-cups by eliminating the unscrewing and fittingtogether of the threaded interengaging of the cap and the body; toprovide a cylindrical casing, screwed over the body of the device, withan open upper end to make the refilling possible from the upper end ofthe device; to provide the lower end of the casing with a shoulderpreventing the casing from being unscrewed; to provide interlockingmeans near the upper edge of the casing; to provide a cap to close theupper open end of the casing having suitable cut-outs or recesses toengage with the interlocking means on the casing; the inventionconsisting in the construction, combination and arrangement of deviceshereafter more .fully described and claimed, and illustrated in theaccompanying drawing, in which Figure 1 is a vertical cross sectionthrough the device. Fig. 2' is a side view of the cap. Fig. 3 is aslightly modified construction of the cap in cross section. Fig. 4: is asection on line H of Fig. 3.

Similar numbers refer to similar parts throughout the papers.

The body 1 of the device is provided on the upper end with a shortcylindrical part 2, threaded on the outside. A casing 3, threaded on theinside fits turnably on the threaded end of the body having a shoulder 4on the lower end preventing the casing from being unscrewed in upwarddirection.

It will be understood that the device is placed on top of or near abearing so that it may supply the latter with lubricant, and the casing3 of my device cannot be unscrewed in downwardly direction as the deviceis normally too close to the bearing to allow a shifting to such anextent. The threads on a grease-cup are usually rather loosely fitting,and, after re-filling the cup, it very often happens that the threads do.not catch right and very soon are spoiled.

A main feature of my device is to eliminate this trouble of ruining thethreads by constructing my device so that it can easily be re-filledwithout having to unscrew it.

Near the upper end of the casing 3 I provide projections or pins 5 as alocking means. The cap 6 fits over the casing 3 having cutouts 7 toengage with the locking means on the casing, see Fig. 2. In Figs. 3 and4, a slightly modified construction of the cap is shown having suitablyformed recesses 8 instead of the cut-outs 7 shown in Fig. 2.

Disengaging the cutouts or recesses of the cap 6 from the projections orpins 5 of the casing 3, the device can be re-filled from the top, and,after the re-filling the cap is engaged again as before, making cap 6and casing 3 one member to be screwed in the same manner as otherwell-known greasecups. To make the upper end of the device tight, agasket 9 is placed between the cap 6 and the casing 3.

Having thus described my invention, I claim 1. A grease-cup consistingof a bodymember, a casing movably engaging with the body member havinglocking means near the upper open end of the casing, and a cap fittingover the upper end of the easing engaging with the locking means.

2. A grease-cup consisting of a bodymember having a threaded cylindricalupper end, a casing turnably fitting with the lower end on the threadedupper end of the body-member having a projection near the upper end, anda cap fitting over the upper end of the casing engaging with theprojection on the casing.

. 3. A grease-cup consisting of a bodymember having a cylindrical upperend threaded 0n the outside, a easing-turnably end of the casingengaging with the lockfitting with its lower end on the threaded ingmeans on the casing. 10 upper end of the body-member having a Intestimony whereof I hereunto affix my locking means near the upper endof the cassignature in the presence of two witnesses.

ing, a shoulder formed on the lower end of ISAAC H. ROHRER.

the said casing engaging with the body- Wltnessesz member adapted toprevent the casing from OTTO H. RINEZER,

unscrewlng, and a cap fitting over the upper C. MITSOHLER,
